 Surya (the sun-god) and Chandra (the moon-god) alert Vishnu to this deception.Vishnu then decapitates Svarbhanu just as he is about to swallow the nectar, leaving his head and decapitated body immortal.Later the head part is known as Rahu and the beheaded part is known as Ketu.According to the Bhagavata, the products of the churning of Kshirasagara are the substances "Halahala" (the terrible poison neutralised by Shiva) and "Amrita" (the divine nectar); the divinities Dhanvantari (the physician of the Gods), Lakshmi (Goddess of Riches), Jyestha (Goddess of Poverty) and Chandra (the Moon); the animals Airavata, the white elephant and the horse Uchchaisrava and, last but not least, the magical wish-granting tree Kalpavriksha.
